HDTV PBS Nova - Kings of Camouflage, 720p!
http://i11.tinypic.com/4vsr6zq.jpg
"Join NOVA on a voyage beneath the waves, where you'll discover a bizarre, alien-like creature like no other. It's an animal with eight sucker-covered arms growing out of its head, three hearts pumping its blue-green blood, and a doughnut-shaped brain. It has the ability to change its color and shape to blend in with seaweed and rocks, and it has a knack for switching on electrifying light shows that dazzle its prey. Perhaps most surprising of all, this animal is quite intelligent, with a highly complex brain. In this program, underwater cameras capture the extraordinary, transformative powers of the cuttlefish.
Not a fish at all, the cuttlefish is a cousin to the more well-known octopus and squid. Together, they are a part of the class of marine mollusks (soft-bodied animals without a spine) called cephalopods, or "head-footers." But while cuttlefish are lesser known, they are very clever. In fact, they have one of the biggest brain-to-body ratios of all invertebrates.
They also have a special talent. Mark Norman, a marine biologist and senior curator from Australia's Museum Victoria, is one of the film's featured experts and has studied cuttlefish for over 20 years. According to Norman, it is the cuttlefish's amazing capacity to rapidly change its color, pattern, and shape that makes this creature so intriguing. By pushing up different parts of its skin, it can camouflage itself against the reef. And with the striking displays of color and light on its skin, it can appear like an alien spaceship hovering in the water, intimidating mating rivals or even hypnotizing a tasty morsel like a crab before attacking it ."
